HP Compaq 6000 Pro Microtower (AT489AV) Power supply upgrade or alternative?

[trentcreek]

Greetings again. I ran into another issue with the computer. It seems fitting a double slot graphics card it not possible due to the CPU cooler in the way.

Any suggestions for an alternative? 

Maybe I should start a new thread

@trentcreek,

Yes, I certainly have this suggestion/solution for you as I applied it to my HP EliteDesk 800 G3/G4/G5 SFF upgrade projects: I used a "90-degrees" PCIe x16 extension cable/graphics card stand/base, like this AliExpress purchase example:

Pulled the PCIe x16 ribbon cable through the desktop's rear PCIe bracket slots and plugged it in the desktop's PCIe x16 slot, and parked my graphics card outside the case -see the blue line:

If your power supply is fitted inside your desktop, you could also pull the PCIe 8-pin power cable(s) the same way to power your GPU. Later used a sturdier (LED lighted) graphics card base:

Hope this was helpful.

Thanks for the quick and informative reply.

I don't think that would be a good match in my case due to many reasons including a young child who will be using this unit.

So the image is what I am dealing with. 

Looking at low profile coolers, even they appear they could be too high. I was looking at Tower Coolers, but they never post all sides, and the dimensions.

@trentcreek,

All right, let's see how we can remedy this.  Please take the same picture at the same angle without the GPU.

Here you go:

Edit:

I found this on NewEgg, and the description indicates support for LGA775

It appears like it could allow the graphics card some space, but they do not show an image of the installation kit.

@trentcreek,

It's definitely a space issue.  Since I have had experience modifying a number of heatsinks, my thinking was that I would trim the heatsink if it wasn't more than, say, 1½ cm.

Btw, what's the part number of the heatsink?

Kind Regards,

The heatsink part number is  577493-001

It does appear that Cr-1200 Cooler from China could work out. Found some images on eBay

Reexamining, no. I see the current heatsink also stops at the same spot as the CR-1200; right at the edge of the metal CPU  holder.

@trentcreek,

Trimming* the heatsink is an option, though HP wouldn't approve, of course [disclaimer]:

Anyway, if you were to consider this, I would strongly recommend offsetting the loss of cooling ribs/aluminum by adding some copper cooling strips, like what I did here with my HP Compaq 8300 USDT upgrade project:

These heatsinks are very inexpensive, under $6 via eBay-US: HP Compaq 6000 6005 ELite 8000 SFF Socket T/LGA 775 Desktop Heatsink 577493-001 | eBay, so you could make this a little 'project' without breaking the bank.

Apparently, there are two different types of p/n: 577493-001 heatsinks (though it doesn't really matter):

* For these kinds of trimming/modding activities, I have used tools like these ones:

Thanks for the time and tips you provided.  Searching, I found those "copper strips" are actually M.2 SSD drive heatsinks.

I did see some water cooling options. The inexpensive option puts the pump and cooler in a single package which raises the height too much. The expensive option does bring the height to an acceptable level allowing the graphics card to fix, but those are overly complex and expensive for such an old computer.

 I would prefer not to cut, but appears I will have to.

Thanks again for time and tips!

@trentcreek,

Any time -glad I could assist!
